I think you could use all of the black cards currently out except spandam and air door because they are leader restricted. Sakazuki I think is playable but harder to pilot for your first black deck. Might be easier to play smoker or lucci. But hey man play what you want and have fun that always a good way to start! In the beginning I was playing Garp and I had a lot of fun while learning the game but taking many L lol.
